• The Ultimate Roster – Twelve new legends from Marvel and Capcom join the fray, bringing the roster of characters on the disc up to 48, and a total of 50 with DLC.
• More Legends – : Includes some of the most iconic and celebrated characters from the Marvel and Capcom universes, including Strider and Firebrand from the Capcom side and Ghost Rider and Hawkeye from the Marvel universe.
• Newly Balanced – Ultimate Marvel vs. Capcom 3 offers re-balanced gameplay that will provide accessible depth for both newcomers and pros alike.
• Enhanced Modes – After many fan requests, Spectator mode is now available as part of an overall improved online experience along with other new modes and enhancements.
•Low Price – The ultimate Marvel vs. Capcom experience can be had at a low MSRP of $39.99.

Just like how Super Street Fighter 4 was with new characters and a very reasonable price, this is no exception. With a low price of 39.99 and 12 new characters bringing the total roster of characters to 48 with 2 DLC planned after release is good to hear. Confirmed characters so far are Strider, Hawkeye, Ghost Rider and Firebrand, the villain in Ghost and Goblins. this is really a good deal even though it's another disc to buy, and you whats better? it's coming sometime in November!

Re-balancing of characters are also included, and the new UI looks amazing.

So far 4 new characters have been revealed, so that means there's still 8 more until November.

UPDATE

Thanks to Tupasheep for this info, the full roster of Ultimate Marvel vs Capcom 3 has been leaked.

Capcom:
Strider
Firebrand
Vergil
Frank West
Phoenix Wright
Nemesis

Marvel:
Ghost Rider
Dr Strange
Nova
Rocket Raccoon
Hawkeye
Iron Fist

Pretty interesting lineup. Phoenix Wright!? Nemesis??! Dr. Strange??! can't wait to see how they play. The leak seems legit enough, it's only a matter of time when we see gameplay reveals of the new characters. When i heard that 8 more were to be revealed soon, i was hoping Marvel characters like Carnage or Gambit, but i guess this will do.
